/// <summary>
/// Creates a custom lifestyle using the supplied <paramref name="lifestyleApplierFactory"/> delegate.
/// </summary>
/// <remarks>
/// The supplied <paramref name="lifestyleApplierFactory" /> will be called just once per registered
/// service. The supplied <paramref name="lifestyleApplierFactory" /> will be called by the framework
/// when the type is resolved for the first time, and the framework will supply the factory with a
/// <b>Func<object></b> for creating new (transient) instances of that type (that might
/// have been <see cref="Container.ExpressionBuilding">intercepted</see> and
/// <see cref="Container.RegisterInitializer{TService}">initializers</see> might have been applied).
/// It is the job of the <paramref name="lifestyleApplierFactory" /> to return a <b>Func<object></b>
/// that applies the proper caching. The <b>Func<object></b> that is returned by the
/// <paramref name="lifestyleApplierFactory" /> will be stored for that registration (every
/// registration will store its own <b>Func<object></b> delegate) and this delegate will be
/// called every time the service is resolved (by calling
/// <code>container.GetInstance<TService></code> or when that service is injected into another
/// type).
/// </remarks>
/// <param name="name">The name of the lifestyle to create. The name is used to display the lifestyle
/// in the debugger.</param>
/// <param name="lifestyleApplierFactory">A factory delegate that takes a <b>Func<object></b> delegate
/// that will produce a transient instance and returns a delegate that returns cached instances.</param>
/// <returns>A new <see cref="Lifestyle"/>.</returns>
/// <exception cref="ArgumentNullException">Thrown when one of the arguments is a null reference
/// (Nothing in VB).</exception>

/// <example>
/// The following example shows the creation of a lifestyle that caches registered instances for 10
/// minutes:
/// <code lang="cs"><![CDATA[
/// var customLifestyle = Lifestyle.CreateCustom("Absolute 10 Minute Expiration", instanceCreator =>
/// {
/// TimeSpan timeout = TimeSpan.FromMinutes(10);
/// var syncRoot = new object();
/// var expirationTime = DateTime.MinValue;
/// object instance = null;
///
/// // If the application has multiple registrations using this lifestyle, each registration
/// // will get its own Func<object> delegate (created here) and therefore get its own set
/// // of variables as defined above.
/// return () =>
/// {
/// lock (syncRoot)
